West African Gaboon Viper

More Information

Adult West African gaboon vipers are around 4 feet long and have leaf-shaped heads with large nasal horns. They feature intricate patterns with gray, brown and green geometric shapes.

These slow-moving snakes are nocturnal and live in rainforests, moist savannas, and forest edges. They spend time in leaf litter, where they are well camouflaged. They are also viviparous, so they give birth to developed 13–15 live young after a gestation of 12 months.
